AN2015 - PSoC® 1 - Getting Started with Flash & E2PROM

2018 年 2 月 19 日

AN2015 enables the reader to get started with the flash memory in PSoC® 1 by focusing on PSoC 1 flash architecture Read, Write algorithm, Protection modes and their impact on user applications. The example projects demonstrates the two methods for reading and writing to the flash memory within a user application, E2PROM User Module and Flash block API library that is included in the PSoC Designer™ integrated development environment (IDE).


Flash operations executed by user firmware are a key element of many embedded designs. The ability for a device to update its own flash is useful in many applications including bootloaders and applications that need to store nonvolatile information such as calibration data.
